Performance of pgAdmin 14 Beta 1

Hi

I've noticed the performance of version 14 is noticeably worse than 
version 12 when clicking on tables.

~0.1 seconds for V12 comapared to ~0.5 seconds in V14.

Looking at the logs I see that the details for all the tabs are selected 
by V14 but in V12 only the details for the current tab of the property 
pane are selected.

As the additional tabs are used much less frequently by me and my users 
couldn't they be lazy loaded as they were in V12?

Many thanks

Kieran

For reference the slow queries are the 4th, 5th and 6th in the log:-
